Least Concern

Dot-winged Antwren (Microrhopias quixensis)


Taxonomy

Taxonomy:

Thamnophilus quixensis

Cornalia

, 1849,

eastern Ecuador

.

Races boucardi and virgatus intergrade in Honduras; research may indicate that they should be merged. On basis of vocal and plumage differences, and perhaps also differences in habitat preferences, some other races may merit elevation to species rank, e.g. emiliae fairly distinctive (although vocal differences minimal); further study required. Name consobrina is invariable (contra HBW)#R. Ten subspecies recognized.
